How do you handle errors in React applications?

Handling errors in React is done using Error Boundaries. They are React components

that catch JavaScript errors anywhere in their child component tree and log those errors or

display a fallback UI.

Example of Error Boundary:

class ErrorBoundary extends React.Component {

constructor(props) {

super(props);

this.state = { hasError: false };
}

static getDerivedStateFromError(error) {

return { hasError: true }; // Update state to trigger fallback

UI

}

componentDidCatch(error, info) {

console.error(error, info);

}

render() {

if (this.state.hasError) {
return <h1>Something went wrong!</h1>;
}
return this.props.children;
}
}

You wrap your components inside ErrorBoundary to catch and handle errors gracefully.
